That should be right, because the absolute value of -9 would be 9, but the negative sign in front makes it -9.

Your selected answer is correct because the absolute value of -9 is 9, and the negative sign outside the absolute number symbols makes it 9 negative, so -9=-9. BUT, we notice that there are choices for "greater than or equal to" and "less than or equal to". Those ones are correct too because it can be one or the other (greater than or equal to, less than or equal to).

Equal to, less than or equal to, greater than or equal to (Choices 3, 4, and 5)

Ryan is buying batteries for his remote control cars. Charge Zone batteries cost $15.80 for 20 batteries. Electrocell batteries

Montano1993 [528]

Answer:

Charge Zone

Step-by-step explanation:

If Charge Zone (CZ) costs 15.80 for 20, and Electrocell batteries (EB) costs 8.10 for 10 batteries, you would find the price and quantity amount by multiplying by two. 8.10x2= 16.20, which is more than CZ.

Therefore, CZ is of better value.
